Make sure none of the other wires are touching one another! The shell can also be put back together with little effort. If you try to exceed mA, bad things can happen. This post was a life saver, and really saved me a LOT of money! March 13, , 6:

A bunch of weird solder jumpering tx and gnd were solder jumpered…rst and vcc were blobbed together Serisl think…some other stuff. Rx ttyS0 Pin 7: Victor March 14, at 7: By Servet — March 4, The methods described here should work in general for cables using different chips.
Void Main’s Serial Port Mods and Console Cables
You should notice a new ttyUSB is added after you connect the cable. That does look like a good deal if you live sserial the UK. With the board still screwed in, and the serial header at the bottom, the holes from left to right are:.
Thanks for clearing this up for me! These cables vary a good bit. I had a 6 conductor wire cat5 8 conductor would have worked too that I used. Attach the black cable to the wire which corresponds pin 8 GND.
Nokia pop-port LIKE-DKU-5 or CA-42 cable schematic pinout
I also had two additional wires, one green pin 3one red pin 4. Don’t poke too much bare copper through the holes, or you’ll touch the grounded steel of the chassis and cause a short-circuit once the device is powered on, 3 mm of bare copper seemed to be enough.
From a OpenWrt Forum https: The Auto-reset input can be ignored and capacitor C1 can be left off. DKU-5 is an old Nokia usb cable adapter and has the chip we want inside, no point in going into details right now about that.
The small LED on the Arduino board, next to the digital pin 13 marked as ‘L’ blinks each seriak if you upload this program.
To do this cut the cable a couple of inches 5 cm from the phone connector.
Get a free blog at WordPress. Don’t ask me why, I just got carried away.
The device when attached to window7 it gets COM5 and recognized by windows…you can see the pictures in the following thread. Unfortunately i have no good experience with cheap chinese DKU-5 but i have found CA cable the best for me… It has only three wires.
Servet says Cool, glad if it helps.
Precautions Never work on a live circuit! My new Arduino USB cable worked great! I can easily find out which of the 3 wires went to where, but how should I find the pinouts of the other pins?
The prolific ones do not work on my laptop Windows 7 bit. Outside of the blue layer I had to use clippers to get it outthere was segial black layer also. I think the manufactures buy these cable based on how cheap they are with little concern for how many wires they have.
Unplug the USB cable. I said the phone connector not the USB connector. RS uses a negative voltage setial a logical 1 and a positive voltage for a logical 0. Don’t touch anything in the power supply area! March 12,8: The rest of this page describes how to connect up your internal serial port.
